Problems solved by technology

[0005] In the prior art, the bed sheet is fixed by Velcro, and the grooves and through holes on the surface of the bamboo mat are added to obtain a better ventilation effect. However, the bamboo material itself has poor moisture absorption and moisture conduction ability for a large amount of sweat, which will still cause the mat to lose moisture. Adhesion to the user's skin, thus giving the user a poor experience

Abstract

The invention discloses a superfine fiber mat and a preparation method thereof, and relates to the technical field of home textile products. A kind of superfine fiber mat provided by the present invention and its preparation method and preparation method thereof, through the preparation process design of segmental segmented PA6 / HDPE composite ultra-short fiber, and the segmental segmental type PA6 / HDPE composite ultra-short fiber is developed The superfine fiber non-woven fabric of the upper layer is prepared through the process of fiber, mixing and forming into a net, and the superfine fiber mat is prepared by compounding with the warp-knitted spacer cloth of the lower layer. The fast moisture absorption and moisture conduction performance and the bulkiness and elasticity of the warp-knitted spacer fabric in the lower layer solve the technical problems of poor sweat absorption and sweat-wicking ability of existing mats and poor user experience, and help to improve the use of mats by users It can avoid various skin problems caused by the adhesion of sweat on the surface of the mat to the skin of the human body.

Description

technical field [0001] The invention relates to the technical field of home textiles, in particular to a superfine fiber mat and a preparation method thereof. Background technique [0002] Summer mat is a necessary product in summer and early autumn. It is used to provide a comfortable environment for people to lie down and rest. An ideal summer mat should have two functions at the same time. While absorbing sweat quickly, it can also play an auxiliary role in cooling to a certain extent. The second is that it feels delicate and soft to the touch and has good skin-friendly properties. There are many types of summer mats, such as straw mats, bamboo mats, rattan mats, cowhide mats, linen mats, and ice silk mats used in air-conditioned rooms that are more popular in the market in recent years. Most of these mats can basically satisfy The above-mentioned second function is also more convenient to use, but there are still defects in fast sweat absorption and moisture removal, th...
